Current Status
- Shift Summaries
- Today (12/16)
- Currently in the second cycle of Setting 1 of HMS high x at 35 degrees.
- BCM Calibration scheduled for 9:30 AM.
- Yesterday (12/15)
- BCM calibrations did not work, as the unser was saturated.
- Dave Mack came in and power cycled it.
- Should be good to go for another BCM calibration, although 60 uA may still saturate, which Dave G says is fine.
- PSS Failure: Hall C suddenly dropped to Restricted Access around 4pm.
- Hall Swept and Run-Save Boxes armed. Back to Beam permit around 5:30 PM.
- Unable to send stable 40uA beam until about 7:30 pm due to thunderstorms.
- Smooth data collection afterwards and through the night, although HMS CODA needed to be restarted once.
- BCM calibrations did not work, as the unser was saturated.
Current Run Plan
- BCM Calibration planned for 9:30 AM Dec 16 (this morning)
- Continue with run plan printed sheet. High x HMS at 35 degrees.
Notices in Effect for Shift Crew
- Continue to fill out SHMS excel sheet for good electrons .
- Keep SHMS prescaled rate below 8kHz.
Current Issues
- HMS Dipole NMR lock struggling to hold. Should be fine, as when it does lock for a few minutes at a time, it is reading back the correct field. May make chaining to the new HMS momentum difficult.
